[PATCH,testsuite] Disable certain tests for 16-bit targets and some for picochip

[Hariharan <hariharans at picochip dot com>]

Hello all,
The attached patch disables certain tests for all 16-bit targets (the 
test contains some assumption about int being 32-bit). It also disables 
a couple of tests just for picochip target. On Janis's advice, i have 
added support for "freestanding", based on the meaning from Section 4 of 
C99 standard.

Of course, any other target that is freestanding could be added to the 
check_effective_target_freestanding function and I intend to send 
another patch with more tests disabled for freestanding targets.

Please let me know if this is okay to commit.

Cheers
Hari
